Korenix JetNet 5310G, the revolutionary DIN Rail type industrial Gigabit managed Power over Ethernet Switch is designed with eight 10/100TX PoE injector ports and two Gigabit RJ-45 / SFP combo ports for highly critical PoE applications such as real time IP video surveillance, WiMAX systems and Wireless APs. All of the 8 ports of the switch are compliant with both IEEE 802.3af PoE and IEEE 802.3at high power PoE standards and can deliver up to 15.4W and 30W power per port to enable the high-power requiring devices, such as Wireless APs, PTZ and dome network cameras, etc.
The two Gigabit Ethernet combo ports provide high speed uplink to connect with higher level backbone switches with Korenix MSRTM network redundancy technology, while ensuring the reliability of video transfer through the exclusive 5ms recovery time. By supporting various connection types, including 10/100/1000Mbps RJ-45 copper or 100Mbps, 1000Mbps Fiber, the Gigabit uplink ports further enlarge the ring infrastructure.
With IEC 61000-6-2 / 61000-6-4 Heavy Industrial EMC certified design, including robust enclosure and -40~75oC wide operating temperature range, JetNet 5310G ensures high performance of the surveillance network under vibrating and shock environments in rolling stocks, traffic control systems and other harsh surveillance applications.
Driving the IP Surveillance Market
Since the ratification of the Power over Ethernet standard in 2003, the PoE technology becomes a trend; more devices adopt PD function to obtain power through Ethernet cable eliminating the need of running separate power wirings to a remote device. The JetNet 5310G is equipped with the new PSE solution, compliant with IEEE 802.3af, IEEE 802.3at 2-event or IEEE 802.3at 2-event with LLDP standards, as well as forced mode powering mode for legacy Power over Ethernet cable devices.
The 8 PoE ports support LLDP power negotiation function or 2-event classification of IEEE 802.3at PoE Plus, and can therefore deliver up to 30W power per port and 80W per unit at 75oC operating temperature, to drive the IP cameras for cross-street monitoring or WiMAX systems for internet access at train stations, airports or Hot-spots.
100/1000Mbps DDM SFP Transceiver for High Quality Monitoring
The SFP socket of the JetNet 5310G supports 100Mbps and 1000Mbs SFP type fiber transceivers with speed detection and independent indication. Moreover, it supports DDM (Digital Diagnostic Monitoring) type SFP transceivers allowing users to diagnose optical cable transmission problem through maintenance and debugging of the optical signal quality by DDM without the need of an extra optical cable analyzer, as a result greatly saving time and system costs.
Rapid Super Ring (RSRTM) Technology
The JetNet 5310G supports Rapid Super Ring technology, which is the 2nd generation of Korenix Ring Redundancy technology. The recovery time is greatly improved from 30ms to few ms for both copper and fiber ring. The Ring master can be auto-selected by RSR engine. The 1st ring port of the R.M. is the primary path while the 2nd ring port of the R.M. is the block path. Once the primary path fails, the 2nd path will be recovered within few ms. Besides, the restoration time is also shortened to zero in the R.M. auto-selection mode.
Comprehensive Redundant Solutions – Multiple Super Ring (MSRTM)
JetNet 5310G also supports advanced Ring technology – M.S.R. (Multiple Super Ring) which includes various new technologies for different network redundancy applications and structures. The supported MSR allows JetNet 5310G aggregating up to 5 Rapid Super rings includes 4 Fast Ethernet plus 2 Gigabit Ethernet rings into one switch. With the MSRTM technology, a node can be configured to multiple rings with the failover time. In addition, users can extend the ring topology by adding hundreds of JetNet series to meet the large-scale network needs without compromising the network speed. The MSRTM also allows the JetNet 5310G managed switch to easily connect with core management switches via standard Rapid Spanning Tree Protocol or through multiple paths or nodes to increase the reliability by RDHTM (Rapid Dual Homing) technology. By integrating MSRTM and Link Aggregation Control Protocol (LACP) the JetNet series can enhance the link availability and increase the overall link capacity. Two or more Fast Ethernet connections are combined in order to increase the bandwidth and to create a resilient and redundant link.
Seamless Ring Port RestorationTM
Seamless restoration is a new Korenix patented technology which can restore a failed ring without causing any loop problem, topology change and packet loss. With a zero second restoration time, this mechanism eliminates any unstable status and guarantees the applications running non-stop.
Rapid Dual Homing (RDHTM) Technology
Rapid Dual Homing is also an important feature of Korenix new generation Ring technology. It supports ring coupling with other vendors devices. Moreover, providing easy configuration and multiple redundancies, the failover time is much faster and the restoration time is zero ms. Uplinks can be auto detected and gathered into groups. In each group uplinks are sorted into primary, secondary and standbys based on their link speed. The uplink with the highest speed is more likely to be active path for data transmission. Link aggregation is also integrated into RDHTM. An uplink connection can be a single link or several links aggregated as a trunk, which provides better redundancy and link capacity.
Link Aggregation Control Protocol
Link Aggregation Control Protocol allows users grouping multiple Ethernet ports in parallel to increase the link bandwidth. The aggregated ports can be viewed as one physical port, so that the bandwidth is higher than just one single Ethernet port. The member ports of the same trunk group can balance the loading and backup with each other. The LACP feature is usually used when higher bandwidth is needed for the backbone network. This is a cost-effective way for transfering much more data.
TrunkRing is a new feature in MSR which merges the two technologies of RSR and link aggregation. It takes advantages of aggregation to enhance the link redundancy, while increasing the link speed. The ring will open only if all the aggregated links are broken. Link aggregation can be achieved by either static trunk or LACP. Not all the link sections in a TrunkRing need to be the same. Ring links can be either symmetric or asymmetric. Some are a single path, and the others are aggregated by links where the number of links in a trunk group can be different. Users can enhance the link redundancy at different locations in accordance to the need. The link with less speed is more likely to be used as the backup path for restoring the network to full play capacity.
Auto Topology Discovery & Efficient Management through LLDP and JetView Pro i2NMS
JetNet 5310G supports topology discovery or LLDP (IEEE 802.1AB Link Layer Discovery Protocol) function that can help users to discover multi-vendor’s network devices on the same segment by an NMS system which supports LLDP function. With LLDP function, NMS can easily maintain the topology map, display port ID, port description, system description, VLAN ID and so on. Once a link failure happens, the topology changed events are updated to the NMS to help users easily maintain the network system. Like as the JetView Pro, not only supports topology discovery, it also d elivers group IP assignment, firmware upgrade, configuration files backup / restore ,SNMP MIB Broswer /compile, MSRTM group management and also allows user to export topology map to drawing file - JPEG, BMP, PNG or PDF for other application.
Outstanding Management and Enhanced Security
The JetNet 5310G provides various network control and security features to ensure the reliable and secure network connection. To optimize the industrial network environment the switch supports advanced network features, such as Tag VLAN, Private VLAN, QinQ, IGMP Snooping, Quality of Service (QoS), Link Aggregation Control Protocol (LACP), Rate Control, etc. The PoE switch can be smartly configured through JetView, JetView Pro (Korenix’s advanced management utility), Web Browser, SNMP Telnet and RS-232 local console with its command like interface. The failure notifications are sent through e-mail, SNMP trap, Local/Remote system log, Multiple event alarm relay.
To avoid hacker’s attacks and ensure the secure data transmission, JetNet 5310G series features DHCP client, DHCP server with IP and MAC binding, 802.1X Access Control, SSH for Telnet security, IP Access table, port security and many other security features.
